The Fabspeed Porsche 996 Carrera Sport Catalytic Converter X-Pipe is a high-performance exhaust upgrade designed to replace the restrictive factory catalytic-converter section while retaining catalytic emissions treatment.
Fits:
- Porsche 996 C2 3.6L 1999-2004
- Porsche 996 C4 3.6L 1999-2004
Combining a specially developed X-pipe crossover with integrated 200-cell HJS Sport Catalytic Converters, the system is designed to improve exhaust-gas flow, increase horsepower and torque, reduce rear-end weight and enhance the distinctive Porsche flat-six exhaust note.
Constructed from mandrel-bent T304L stainless-steel tubing, the system provides a performance-focused alternative to the factory catalytic converters without using catalyst-bypass pipes.
What This Product Does:
The catalytic-converter section performs two important functions within the exhaust system.
First, it routes exhaust gases from the engine towards the rear mufflers. Second, the catalytic converters chemically process harmful exhaust pollutants before the gases leave the vehicle.
The Fabspeed Sport Catalytic Converter X-Pipe retains catalytic-converter functionality while providing a higher-flow exhaust path.
Its design is intended to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Improve mid-range torque
- Improve high-RPM horsepower
- Enhance throttle response
- Reduce exhaust-system weight
- Produce a more sporting flat-six exhaust note
- Retain catalytic emissions treatment
Performance Benefits:
Fabspeed reports dyno-tested improvements of:
Horsepower: +25 WHP
Torque: +32 ft-lb
Weight Reduction: Approximately 11 lb
These figures are manufacturer-reported results and should not be considered guaranteed output for every vehicle.
Actual performance can vary depending on:
- Engine condition
- Vehicle specification
- Fuel quality
- Existing exhaust modifications
- Intake modifications
- ECU calibration
- Ambient conditions
- Dyno type and testing procedure
Why Upgrading Matters:
The Fabspeed Sport Catalytic Converter X-Pipe is also a performance upgrade, meaning the original catalytic converters do not need to have failed before the system can be installed.
Owners may choose the upgrade for:
- Increased exhaust flow
- Reduced exhaust restriction
- Improved mid-range torque
- Improved high-RPM horsepower
- Enhanced flat-six exhaust sound
- Reduced exhaust-system weight
- High-flow HJS catalytic converters
- Performance-oriented X-pipe design
It can also complement other upgrades such as performance headers, rear mufflers, intake modifications and suitable ECU calibration.
